CentOS7编译安装mysql-5.6.28和编译参数
MySQL 5.5之后的源码包版本，安装方式采用CMake工具编译进行安装，因此在安装最新版MySQL之前，需要提前安装它。CMake是一个跨平台、开源软件构建系统，用于控制软件编译过程及生成独立的配置文件（makefile或者project），可以在编译时选择CMake编译器进行安装需要的软件。CMake官网https://cmake.org/，目前最新版本是3.4.3。
CMake安装方法
# wget https://cmake.org/files/v3.4/cmake-3.4.3.tar.gz
# yum install gcc gcc-c++ make automake
# ./bootstrap && make && make install

编译安装mysql-5.6.28
step1：创建mysql用户、组
[root@www ~]# groupadd mysql
[root@www ~]# useradd -r -g mysql mysql
[root@www ~]# id mysql
uid=996(mysql) gid=1000(mysql) groups=1000(mysql)
[root@www ~]# mkdir /usr/local/mysql
[root@www ~]# mkdir /data/mysqldb
step2：安装必须的软件包
[root@www src]# yum install gcc gcc-c++ ncurses-devel bison bison-devel
step3：编译安装MySQL
1、将下载的mysql源码包解压，并进入其解压目录下
[root@www mysql-5.6.28]# cmake . \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/data/mysqldb \
-DSYSCONFDIR=/etc \
-DMYSQL_TCP_PORT=3306 \
-DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 \
-DDEFAULT_CHARSET=utf8 \
-DEXTRA_CHARSETS=all \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_DEBUG=0
重新cmake需要删除CMakeCache.txt文件
[root@www mysql-5.6.28]# gmake
[root@www mysql-5.6.28]# gmake install
[root@www mysql-5.6.28]# ls /usr/local/mysql/ COPYING README data include man scripts sql-bench INSTALL-BINARY bin docs lib mysql-test share support-files
2、设置MySQL目录权限
[root@www mysql-5.6.28]# chown -R root:mysql /usr/local/mysql/ [root@www mysql-5.6.28]# chown -R mysql:mysql /data/mysqldb/
3、安装系统数据库
[root@www scripts]# chmod +x mysql_install_db [root@www scripts]# ./mysql_install_db --basedir=/usr/local/mysql --datadir=/data/mysqldb --no-defaults --user=mysql [root@www scripts]# ls /data/mysqldb/ ib_logfile0 ib_logfile1 ibdata1 mysql performance_schema test
4、拷贝配置文件my.cnf
[root@www mysql-5.6.28]# cd support-files/ [root@www support-files]# cp my-default.cnf /etc/my.cnf
[root@www support-files]# vim /etc/my.cnf [mysqld] basedir = /usr/local/mysql datadir = /data/mysqldb port = 3306 # server_id = ..... socket = /var/lib/mysql/mysql.sock
5、拷贝启动脚本
[root@www support-files]# cp mysql.server /etc/init.d/mysqld [root@www support-files]# chmod 755 /etc/init.d/mysqld [root@www support-files]# chkconfig mysqld on [root@www ~]# service mysqld restart Shutting down MySQL. SUCCESS! Starting MySQL. SUCCESS! [root@www ~]# netstat -ntlp |grep mysqld tcp6 0 0 :::3306 :::* LISTEN 20708/mysqld
6、设置mysql环境变量
[root@www ~]# vim /etc/profile.d/path.sh #!/bin/bash export PATH=$PATH:/usr/local/mysql/bin [root@www ~]# source /etc/profile [root@www ~]# mysql Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 1 Server version: 5.6.28 Source distribution Copyright (c) 2000, 2015, Oracle and/or its affiliates. All rights reserved.

Type '\c' to clear the current input statement. mysql>
7、初始化MySQL及相关安全选项配置
[root@www ~]# mysql_secure_installation NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! In order to log into MySQL to secure it, we'll need the current password for the root user. If you've just installed MySQL, and you haven't set the root password yet, the password will be blank, so you should just press enter here. Enter current password for root (enter for none): OK, successfully used password, moving on... Setting the root password ensures that nobody can log into the MySQL root user without the proper authorisation. Set root password? [Y/n] y New password: Re-enter new password: Password updated successfully! Reloading privilege tables.. ... Success! By default, a MySQL installation has an anonymous user, allowing anyone to log into MySQL without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? [Y/n] y ... Success! Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? [Y/n] y ... Success! By default, MySQL comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? [Y/n] y - Dropping test database... ... Success! - Removing privileges on test database... ... Success! Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? [Y/n] y ... Success! All done! If you've completed all of the above steps, your MySQL installation should now be secure. Thanks for using MySQL! Cleaning up...
